Polarizing power refers to an atoms ability to pull an electron toward it, polarizing the atom the electron comes from. Since cations are positive, they are able to attract electrons toward themselves. Anions are negative and so do not attract more electrons.

Polarizing power and polarizability refer to cations and anions respectively and helps determine the covalent character of ionic bonds. For example Na+ and Cl- are the cation and anion in the ionic bond NaCl. Na+ has a polarizing power which distorts the electrons of the chlorine and attracts them towards the sodium atom. Chlorine's tendency to have its electrons distorted is referred to as polarizability.
